This is GPS, the global public square. Welcome to all of you in the United States and around the world.

I'm Farid Zakaria coming to you from New York City.

Today on the show,

as big an intelligence failure as Pearl Harbor.

That is how the New York Times' David Sangler describes the recent hack of US computer systems.

All fingers point to Russia as the perpetrator.

I will ask Sangler just how bad the intrusion is for national security.

And I'll ask former national security adviser Tom Dunlum how America should respond to Russia and what else the Biden team should be ready to focus on.

And the COVID crisis in America is worsening by the day.

2021 will bring some relief.

But how much?

Will the world return to normal next year?

Global health expert David Sridhar joins me with the answer.

But first, here's my take.

The more we learn about the recent hack into dozens of America's most critical computer networks, widely attributed to Russia-linked hackers,

Tom Bossert who served as Homeland Security adviser to President Trump writes,

it will take years to know for certain which networks the Russians control and which ones they just occupy.

We do know that they successfully penetrated the Department of Homeland Security's own systems as well as the State Department, Commerce and others.

Stanford's Alex Stemos says this is one of the most important hacking campaigns in history.

Vladimir Putin's Russia has significantly expanded its hybrid warfare using new methods to spread chaos among its adversaries.

The United States will have to fortify its digital infrastructure and respond more robustly to the Kremlin's mounting cyber attacks.
